    • A system for selectively controlling visibility of information in an environment is provided. The system includes one or more polarized emissive screens and polarized non-emissive surfaces located within the work environment. The screens have a first direction of polarization and the surfaces have a direction of polarization substantially aligned with the first direction of polarization. Information displayed on the screens and surfaces are visible to a person inside the work environment. The work environment includes at least one window which permits viewing of the polarized emissive screens and non-emissive surfaces from outside of the work environment. A polarizing filter having a second direction of polarization arranged at an angle to the first direction of polarization is positioned proximate to the window. A person outside the work environment can see inside the environment through the window, but has an altered view of the information on the displays and surfaces.
    • 提供了一种用于选择性地控制环境中的信息的可见性的系统。 该系统包括位于工作环境内的一个或多个偏振发射屏幕和偏振的非发射表面。 屏幕具有第一偏振方向,并且表面具有基本上与第一偏振方向对准的偏振方向。 屏幕和表面上显示的信息对工作环境中的人员是可见的。 工作环境包括至少一个窗口,其允许从工作环境的外部观察偏振的发射屏幕和非发射表面。 具有与第一偏振方向成一定角度排列的具有第二偏振方向的偏振滤光器位于窗口附近。 工作环境以外的人员可以通过窗户在环境中看到,但是对显示器和表面上的信息进行了更改。
